100% better sleep
I’ve been supporting Oura since it was a kickstarter. I had the version 3 and decided not to upgrade but since my spouse lost her ver 3 I gave her mine and ordered this.If you’ve never had an Oura ring: this product is amazing. So comfortable, more so than a watch. The app is great, I’ve learned so much about sleep habits, what to do and not to do for sleep. Lovers of science will like this, you can literally experiment and see the exact results for yourself.Accuracy: I would say this is 95% accurate. Again, I’ve been using this for about 5 years. So I’ve seen the accuracy improve IMMENSELY over the years. Version 4 is the best yet. Better than any other sleep tracker I’ve tried and I’ve tried a lot. The biggest inaccuracy is every now and then I’ll get up to pee in the middle of the night and it will think I woke up for the day. Sometimes it knows I just went to pee sometimes not. Since I noticed it, I take my ring off if I get up to go to the toilet and it fixes the issue—just don’t forget to put it back on!Key info for consumers: the fit is slightly larger than the version 3. To be exact I would say the version 4 is about half a size larger. So the new size 7 for example, would be a size 7.5 on the old version 3 and older models.The new size is great for me. My old ring was snug on my ring finger. So now I can wear the new one on my pointer finger and even middle finger depending on how hot it is. It all depends on the temperature outside due to our hands expanding/shrinking in heat/cold. Hot days I’ll wear on my ring finger, cold days I can wear on my index or middle finger.Conclusion: I love the Oura ring. It’s more comfortable than an Apple Watch or a woop in my experience. Way, WAY more comfortable. It’s also very accurate and the info is extremely useful. It’s increased my understanding of sleep, the importance of exercise for sleep, and dare I say, made me a better person. Getting better sleep takes effort, and this is merely a tool to help you do that. Getting better sleep can 100% make you a better person and I speak from my own experience.

Didn’t know I would love this so much
This has been so much better than an Apple Watch. From being able to comfortably sell wearing my Oura ring, to giving me valid, easy to understand health information and advice, I have been very impressed with my purchase. I also love how quickly it charges – I can shower and come back to a full charge in 15 minutes. I love the sleep tracking insights, reminders based on my health data and feel like I can see the value. Things I would love to see in the future are more app integrations listed. I know it syncs to apple health, so most apps will integrate, but would love to see a more robust list within Oura’s app. I’d also love to see a less bulky version in future models. I have tiny fingers so it is incredibly noticeable, but worth it for the value. In hindsight, I should e paid more for the gold to match with all my other jewelry. I didn’t know I’d be this happy, so I’m willing to overlook that detail (just a recommendation that it might be worth considering if you wear other jewelry regularly).
